    HI,
    i need to find replacement parts for the "AD620" and "OPA2277PA" for my project.. i've tried using websites like allxref.com and i ended up with a list of replacements which is good ... the problem is that i couldn't understand what does ( Pin-to-Pin Replacement, Compatible Equivalent, Functional Equivalent and Possible Analogue ) mean :confused: ?

    your help is much appreciated .

    Looks to me like a probablility rating that the proposed component can be used as a replacement. From more likely to less likely in the same sequence as you posted.

    Anyway , you will always have to check the main parameters, like max supply voltage, input voltage range and others depending on your application.

    I would guess that "Pin-to-Pin Replacement" is very likely to have the same characteristics.

    Go to www.farnell.com and click on the flag of your country or a country nearby.
    They and their new name Element14 sell electronic parts all over the world from many warehouses. The AD620 is a very common part.

    thank you gentlemen for your replies
    that's exactly what i thought..now i guess i just need to go through some datasheets..

    yes i've already tried buying from them, they have a good per-unit pricing.. the only problem is that they charge so much on shipping that's why i've been trying to find a replacement so i can buy it locally..

    THANK YOU again for your replies
